Question

the ages of Sunita and Rohan are in the ratio 5
: 7 four years later the ages will be in the ratio 3: 4 find the ages​

Answer 1

Answer:

Step-by-step explanation:

5x + 4 +7x + 4 = 56

or 12x + 8 = 56

Transposing 8 to the RHS we get,

12x = 48

Dividing both sides by 12 gives,

x = 48/12 = 4

Thus current age of sunita = 5*4 = 20

rohan

= 7*4 = 28
